Studies of entanglement in many-particle systems suggest that most quantum critical ground
states have infinitely more entanglement than noncritical states. Standard algorithms for one …

Critical phenomena arise in a wide variety of physical systems. Classi cal examples are the
liquid-vapour critical point or the paramagnetic ferromagnetic transition. Further examples …

Most quantum system with short-ranged interactions show a fast decay of entanglement with
the distance. In this Letter, we focus on the peculiarity of some systems to distribute …

We study asymptotic expansions of spin–spin correlation functions for the XXZ Heisenberg
chain in the critical regime. We use the fact that the long-distance effects can be described …

We consider the six-vertex model with anti-periodic boundary conditions across a finite strip.
The row-to-row transfer matrix is diagonalized by the'commuting transfer matrices' method …

We study a quantum Ising chain with tailored bulk dissipation, which can be mapped onto a
non-Hermitian Ashkin-Teller model. By exploiting the Kohmoto-den Nijs-Kadanoff …

The history of critical phenomena goes back to the year 1869 when Andrews discovered the
critical point of carbon dioxide, located at about 31° C and 73 atmospheres pressure. In the …

We study Z 3 symmetry-protected topological (SPT) phases in one-dimensional spin
systems with Z 3× Z 3 symmetry. We construct ground-state wave functions of the matrix …

We study integrable vertex models and quantum spin chains with toroidal boundary
conditions. An interesting class of such boundaries is associated with non-diagonal twist …

We study't Hooft anomalies of discrete groups in the framework of (1+ 1)-dimensional
multiscale entanglement renormalization ansatz states on the lattice. Using matrix product …
